<p>PURPOSE:To provide a barrier layer containing inorganic fine particle between a coloring layer and a base layer so as to prevent corrosion of aluminum occurring due to environment and improve environment resistance in a ticket having the coloring layer, base layer, and aluminum thin film layer laminated on a base material. CONSTITUTION:A ticket having a printing layer is constituted such that a coloring layer 2 coated with magnetic coating containing black coating and magnetic powder, a barrier layer 6, a base layer 3 consisting of acryl-silicon resin, an aluminum thin film layer 4, and a protective layer 5 are formed in sequence on a base material 1 consisting of polyethylene terephthalate film. As the barrier layer 6, a resin having excellent insulating property such as urethane resin, acrylic resin, and polyimide resin is used, and the thickness thereof is set to about 1-7mum. In order to generate discharge of the aluminum thin film layer 4 easily, irregularities are made on the surface of the barrier layer 6 containing filler so as to operate as a protrusion for the electric discharge.</p> |
